Some "March Madness" facts and bracket advice from Las Vegas

The next best thing to football season in Vegas is the NCAA men's basketball tournament. The casino sports books are always hopping while the games are being played, especially on the first couple of days of the tournament.

Here are some facts and advice from R.J. Bell of Pregame.com:

2012 NCAA Tournament Action:

Over $12 BILLION worldwide expected to be wagered on NCAA TournamentThat’s more action combined than on the Super Bowl!Less than 1% of worldwide sports betting occurs in Nevada

Over 100 million people expected to take part in tournament bracket contests!

Perfect Bracket Odds:There are 9,223,372,036,854,775,808 possible brackets (9.2 quintillion)That's the number nine follow by eighteen zeros!That’s ONE MILLION times bigger than 9 TRILLION!

Some examples of just how big this number is:

If everyone on the planet each randomly filled out a bracket, the odds would be over ONE BILLION to 1 against any person having a perfect bracket.

If one bracket per second was filled out, it would take 292 BILLION years to fill out all possible brackets (that's 20 times longer than the universe has existed).

If all the people on earth filled out one bracket per second, it would take over 43 years to fill out every possible bracket.

If all possible brackets were stacked on top of each other (on standard paper), the pile would reach from the moon and back over 1.1 million times.

All possible brackets (on standard paper) would weigh 90,000 times more than every man, women, and child on earth combined.

Even if a person had a 90% chance of winning each game he picked, his odds would still be 763 to 1 against picking a perfect bracket.
